Blue Belle: Duchess Kate Shows Off Perfect Maternity Style At Art Charity Event

Excuse us while we ooh and aah, but wasn't the Duchess of Cambridge's baby-blue empire-line dress just the most lovely maternity frock ever?

The Emilia Wickstead number was not only a complementary colour, but was just so simple and chic, and made the ideal look for an evening reception to celebrate the work of The Art Room charity at The National Portrait Gallery.

The Duchess paired it with grey suede Rupert Sanderson heels and a half-up hairdo for a look that other famous mums-to-be should sit up and take note of (ahem, Kim K).

Gorgeous - and how cute is her tiny little bump?
